Make sure your engine is properly grounded as well. I've seen weird electrical issues like this because the engine wasn't properly grounded, and that showed when higher electrical demands (high rpm) were needing the additional ground.
It seems to break up as soon as the rpm increases. The carb that is on it now, I run on one of my daily drivers so I know it works good. It did the same thing with the quadrajet though. I’ll recheck my ground. I thought one lifter plunger felt odd when I was adjusting the valves the first time. One didn’t seem to want to compress like the others did. But the valves are very quiet it seems like.
